Strong Law of Large Numbers of Pettis-Integrable Multifunctions
Journal of Mathematics, 2019 Using reversed martingale techniques, we prove the strong law of large numbres for independent Pettis-integrable multifunctions with convex weakly compact values in a Banach space.

Predict Suitable Restoration Areas for Typical Vegetation Restoration Species on the Qinghai-Tibetan Plateau Based on MaxEnt. [PDF]
Ecol EvolIt was first used in the QTP vegetation restoration species, mainly to provide a basis for species selection in different regions of the QTP now and in the future. Secondly, it calculates the ecological niche overlap and niche breadth to avoid the risk of interspecies competition, providing a basis for the combination of species.

Asymptotics for Time-Fractional Venttsel’ Problems in Fractal Domains
Fractal and Fractional, 2023 In this study, we consider fractional-in-time Venttsel’ problems in fractal domains of the Koch type. Well-posedness and regularity results are given. In view of numerical approximation, we consider the associated approximating pre-fractal problems.

Mosco convergence and the Kadec property [PDF]
Proceedings of the American Mathematical Society, 1989 We study the relationship between Wijsman convergence and Mosco convergence for sequences of convex sets. Our central result is that Mosco convergence and Wijsman convergence coincide for sequences of convex sets if and only if the underlying space is reflexive with the dual norm having the Kadec property.

Fixed Point Theory and Applications, 2010 Motivated by the method of Xu (2006) and Matsushita and Takahashi (2008), we characterize the set of all common fixed points of a family of nonexpansive mappings by the notion of Mosco convergence and prove strong convergence theorems for nonexpansive ...

Multicomponent incompressible fluids—An asymptotic study
ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, Volume 103, Issue 7, July 2023., 2023 Abstract This paper investigates the asymptotic behavior of the Helmholtz free energy of mixtures at small compressibility. We start from a general representation for the local free energy that is valid in stable subregions of the phase diagram. On the basis of this representation we classify the admissible data to construct a thermodynamically ...

The role of cell size in shaping responses to oxygen and temperature in fruit flies
Functional Ecology, Volume 37, Issue 5, Page 1269-1279, May 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract The body size of an animal is strongly coupled to key ecological traits such as fecundity, mortality and growth. Ectothermic animals mature at smaller body sizes in warmer conditions and under low oxygen availability (hypoxia).

Mathematics, 2023 In this work, we used reflexive Banach spaces to study the differential variational—hemivariational inequality problems with constraints. We established a sequence of perturbed differential variational–hemivariational inequality problems with perturbed ...

Functional Ecology, Volume 37, Issue 4, Page 1033-1043, April 2023., 2023 Read the free Plain Language Summary for this article on the Journal blog. Abstract Vulnerability to warming is often assessed using short‐term metrics such as the critical thermal maximum (CTMAX), which represents an organism's ability to survive extreme heat. However, the long‐term effects of sub‐lethal warming are an essential link to fitness in the

On the cross‐validation bias due to unsupervised preprocessing
Journal of the Royal Statistical Society: Series B (Statistical Methodology), Volume 84, Issue 4, Page 1474-1502, September 2022., 2022 Abstract Cross‐validation is the de facto standard for predictive model evaluation and selection. In proper use, it provides an unbiased estimate of a model's predictive performance. However, data sets often undergo various forms of data‐dependent preprocessing, such as mean‐centring, rescaling, dimensionality reduction and outlier removal. It is often
